8440p does support KVM Remote Control and the CPU model you mention does support KVM & Intel Integrated graphics (a requirement for KVM). So, just be sure the laptop you get uses Intel Integrated Graphics and you're good to go! Here's a little more info:

Hi, finally getting around to trying to get the remote KVM feature working. I have AMT working OK, but cannot get the remote KVM feature working.

I cannot find the above setting anywhere in my AMT setup. I am using version Intel Management Engine BIOS Extension v6.0.3.0019/Intel ME v6.0.3.1195. I have all of the AMT 5 features I am familiar with working, just not remote KVM .
